To'all whom it may concern:

Be it known that I, WILLIAM HOWARD SMITH, a citizen of the UnitedStates, i'esiding in Atlanta, in the county of Fulton and State ofGeorgia, have invented a newV and useful Improvement in Orchard-Heaters,of which the following is a specification.

My invention relates to improvements in orchard heaters. f

.The object of my invention is toprovide an orchard heater'of a simple,efficient and durable construction capable of being manufactured andfurnished at small cost, and

which may be easily and quickly assembled,

filled with fuelA and lighted.

My invention consists in the means I. em-

ploy to practically accomplish this object or result as herein shown anddescribed and more particularly specified in the claims; the samecomprising in coperative combination a sheet metal pot or liquid fuelcontainer having an external roll at its upper 4end; an annular sheetmetal top secured thereto 5 a perforated sheet metal chimne or fluemember coiled or curved into cylindrical shape with its meeting edgesoverlapping and fit-V ting within the opening of the annular top andresting atits lower end on the ybottom of the pot or fuel container; acorrugated sheet metal hood of frusto-conical shape, having an inwardlyprojecting annular iiange at its upper end surrounding the upper end ofthe chimney lor iue member, and

with the inner walls of its corrugations at the lower end surroundingand, wedgingly engaging the upper end 4of the pot or fuel container andits annular top secured thereto, to form a seriesof air passagesdistributed uniformly around the whole circumference of the pot or fuelcontainer at the upper end thereof.` The annular top is made ofa squarepiece of sheet metalA the side of ing openings for air passages betweenthe 'annular top and the upper rim of the con-.-

tainer. A cover, preferably of a square piece of sheet metal withitscorners turned atan angle to fit in and engage corrugations of y thehood, is provided to cover the hoo-d and, iue ofthe heater when theheater is notl in luse and exclu'derain. "f

My invention also consists the novel lconstructions of parts and devicesandin the novel combinations of parts -and devices lherein shown anddescribed and more particularly specified in the claims..

`In the accompanying drawing forming apart offthis specificationFigure lis aside 60 elevation of an orchardheater or pot embodying my invention.Fig. 2 is a central .vertical longitudinal section on line'2-2 ofFig; 1. '.Figs. 3 and 4 are horizontal sections on lines 3 3 land 4 4respectively of Fig. 2. I6.5

vIn the-drawing 1 represents the body of a sheet met-al fuel pot orcontainer preferably -of frusto-conical form with its llargervenduppermost and made like the other parts of ordinary black sheet iron orsteel. The body has one 0rmore lock side seams 2 at the meeting edges ofthe blank or blanks from which it is formed andthe bottom 3 is securedto the lower endof the body l by a double Vseam 4 so that all the seamsof the 75 vessel -will beliquid tight for `holding crude petroleum. orother like liquid or semi-liquid fuel and adapted to withstand the heatand re.- At its upper end the body of the vessel is provided with anexternal rolled rim 80 5 which embraces a stiffening wire 6.'-

The annular .top 7 has a large central opening 8 to receive thechimneyor flue member 9 andy it is preferablyfurnished with segmental flanges10 turned under the 85 external rolled rim '5 of the container to securethe annular topY thereto while leaving Vopenings or air passagesllbetween the'annular top and the rim of the-container at the fourrectangular sidesV of thel annular .topfthe segmental curved -ianges 10being formed at the diagonal rounded portions of the square sheet fromwhich the annular top is formed.

AThe chimney or flue 9 is furnished with 95 y curving-a rectangularpiece of perforated lollsheetlmetal into cylindrical form, its meetingedges 13, '14;being`loose or unconnected but overlapping. each other. l

orflue member 49 is open at bot-h ends and The chimney tits,removablywithin` the central opening of the'ann'ular top 'and rests atits lower end -agrinst the bottom?) of the fuel containerl.

` lower end of the hood, the corrugations beingmaterially deeper at thelower end of the hood than at the upperend thereof. The i inner .walls17 of the corrugations 16 wedgingly engage the rim 5 of the container 1I 'and-segmental flanges 10 of the annular top j which may be partly.removed to regulatewhich. embraces therolled rim of the contain'r foraportionof lits circumference.

' This wedging engagement between the lower end of the corrugated hoodand theupper end of the containerl serves to securelyhold the hood 15in. place on the container. The externally projecting walls 18 of theseries of corrugations 16, form a series of air passages oropeningsbetween the rim of the container 1 and the hood to admit airinto.

thecontainer through'the openings 11 between the to 7 and container 1and through the perforatlons 12' in the Hue 9, which are .both above andbelow the annular top 7, to suport combustion of ,the fuel inthecontainer and create a proper draft in the flue 9. The'corrugated hood15 is provided at its upper end withan inwardly projecting annularflange 19which surrounds the upper end' of the cylindrical chimney lorHue mem ber 9.' The4 hood is also provided with an upwardlyprojectingannular head2() at the with the annular horizontally extending ange 19.As the corrugated hoodhas a tight .wedging engagement at its lower endwith the u per end or lrim of the fuel coniiood will beheld firmly' inposi tion.. :.1

The cover 21 which covers the upperV e of the' flue or chimney'piece-'.9 andfof the hood 15 when the `vessel is not in .use orcombustion as desired, may be of any suitable form, such for example asa flat piece of metal, 'a round disk with a'depending an.-

nular flange or a rectangular piece of metal with its corne'rsQE)Jturned at an angle to engage the corrugations 16 of the hoodA 15:

In operationV the body or container 1 is 4filled with-crude petroleumorother cheap liquid or semi-liquid fuel and then ignited, preferably by'atorch orgby. putting al small quantity of waste or-other fibrousmaterial in the container-5 through the flue. The air to'support'combustion enters under thehooc -and passes in part beneath thetopj-platf through the openings l1 between `its sid'f edges. and the rimof the container anel thence passes 'through the holes orperforations inthe iue'member into the flue chamber, combustion being confined or'chie'iy eonlinedto the' surface of the oil insidevthe flue. As the oilin the container is conenmed,A further holes inthe opening are exingsbetwe'eii its side edges and the rim of the container, andl providedwith a central opening, a perforated flue sheet 'rolled into acylindrical form with loosely overlapping edges, and fitting within thecentral opening of said top plate, and resting at its lower end on thebottom of the container, and a frustc Iconical longitudinally corrugatedhood with the inner walls -of'its corrugations. 'wedgingly engaging theouter rim of the con- 'tainer top plate, the outer walls of itscorrugations forming a series of air passages distributed entirelyaround the circumference'of the container, said hood having an inwardlyprojecting annularflang'e at its upper-end surrounding the upper end ofthe Hue, said flange ofthe hood being substantially flush-:with theupper end of theflue -with an annular air passage therebetween junctionof the longitudinal corrugations 16"- Aupper end of theflue and acommoncover plate adapted to close both the upper end oil the hood andthe upper end of the. flue, said cover having downwardly bent andcircumferentially-arranged engaging fingers, subtanially as specified.

An orchard heater,4 comprising in combination a sheet metal fuelcontainer having -an externally rolled rim at its upperl end, a

top plate secured thereto and having openings between its side edges andthe rim oi the container, and provided with afcentral opening, aperforated flue sheet rolled intc cylindrical form withlooselyoverlapping edges, and fitting within the central opening of said topplate, andresting at its lower end -on the bottom'of the container,l anda frustc conical longitudinally corrugated hood with the inner walls ofits corrugations 'wedgingly engagingthe outer rim of the container topplate; the outer walls of its corrugations forming a series of airpassages distributed entirely around the circumference' of the deflectair inwardly from the 'upper end of ontainer, said 1hoog having inwardlythe iu'e,l substantially as specified. projecting annu ar 'ange at itsuper end surrounding the upper end of the filgie, seid WILLIAM HQWARDSMITH' v5 fiange ofthe hood being substantiallyiiush Witnesses:
